I assume GP meant "how it works". Why it works is because the spec says so and the native code behind it makes it. Why does func() work, or 1+1? How it works is func is scheduled to execute asynchronously on the next tick of the event loop at the soonest, so if func() printed "wat" and you have console.log('huh') directly after that statement, you'd see "huh" then "wat"
